Fluctuation when metal scraps and wood scraps get into the eyes during cutting / polishing work. We could not afford expensive protective eyeglasses, we found cheap, transparent and distortion-free products, we found here. Although it is slightly cheap, I think it is a product more than price.

I bought it as a protective equipment to use at work. It was too big to be used with eyeglasses of common size and was used to hook on earlobe, but this protective eyeglasses was perfect. It is recommended for ladies because it is a smaller size.

During polishing work such as Thunder use, metal splashes become an initiator of respiratory or eye diseases, so it is an essential item at work. Although it is not cloudy due to perspiration etc. in winter, use in the future heat is a problem.
